ーボ過給機関。A plurality of exhaust turbo superchargers, and all but one of the superchargers have an exhaust gate valve at the turbine inlet and an intake gate valve at the blower outlet. In an exhaust turbocharged engine in which the number of operating units is variable, an exhaust bypass valve or the above-mentioned air supply partition is provided on the turbine inlet side of a turbocharger where the above-mentioned exhaust gate valve is not provided and discharges a part of the incoming exhaust gas to the outside. A supply air bypass valve is installed on the blower outlet side of a supercharger where no valve is provided and releases a portion of the discharged supply air to the outside, and the above exhaust or supply air bypass valve is connected to the engine exhaust pipe to reduce the exhaust pressure. an exhaust pressure take-off pipe that opens the bypass valve against a valve opening pressure set by a spring; Either one of the supply air bypass valves is in communication with the blower outlet side of the supply air gate valve of the turbocharger provided with the supply air gate valve, and either one of the exhaust air and supply air bypass valves is connected to the An exhaust turbocharged engine characterized by comprising an adjustment pressure take-off pipe that communicates with the valve opening pressure and adjusts the valve opening pressure.
